[ns] Adapting Transmission Power (Pt_) of a node in C++
Dear All, I am working on Network layer in NS2.35. I am trying to adjust a single node's transmission power (Pt_) based on distance to destination node. To do it in TCL, it's pretty easy but when I try in C++, it doesn't work. I will appreciate any possible help. Thanks, Abdul Waheed Khan PhD Scholar @ UTM, Malaysia
[ns] Wifi transmission power
Is there any way to restrict the transmit power (to lower the range) of wifi nodes ? How can I configure this ? In my cenario, the wifi nodes have a large range, but I am simulating RFID tags, so I need to limitate the range.

Re: [ns] for transmission power
Dear Dhara, To let the packet sent by N1 be received by N2, u need to adjust the values of Pt_ and RxThresh_ depending upon the distance between the two nodes. U can get the value of RxThresh_ using a utility shipped with NS2 in a folder named as indep_utils and the utility name is threshold.cc. Refere to some ns tutorial for its usage. As far as value of Pt_ is concerned, i myself is looking for it i.e. how to compute its value for certain distance (SO if u get to know from somewhere how to compute that, do letme know too). By default in NS2, communication range of nodes is 250m and the corresponding values for Pt_ and RxThresh_ are 0.2818W and 3.625e-10W respectively. Goodluck!

[ns] AP transmission power in wifi network
Hi people, I'm Rafiza and I am new to NS2. I am interested on Wi-Fi Load balancing and plan to develop an algorithm by making some adjustment on the AP transmission power. If you don't mind, I need to ask you some questions. My question is, where and what module in NS2 that are related to my area of interest? and should I use ns-2 or ns-3? Thanking you in advance. Regards, Rafiza.
[ns] change transmission power
hi all, i want to change my transmission range, one time i run my scenario with: Phy/WirelessPhy set Pt_ 0.2818 //250 meter another time, with Phy/WirelessPhy set Pt_ 8.5872e-4 //40 meter but no change in results. that the other values are fixed: Phy/WirelessPhy set CPThresh_ 10.0 Phy/WirelessPhy set CSThresh_ 1.559e-11 Phy/WirelessPhy set RXThresh_ 3.652e-10 Phy/WirelessPhy set Rb_ 2*1e6 Phy/WirelessPhy set freq_ 914e+6 Phy/WirelessPhy set L_ 1.0 whats the problem? do i miss something? could anyone give me a step by step procedure to change the transmission power?
Re: [ns] Fw: transmission power change for one node only
Configure and creat that node separately in your TCL script. Configure it according to ur desirable parameters. configure and create the rest nodes alltogether if they have same properties. --- On Thu, 4/30/09, Arslan Munir munir.ars...@yahoo.com wrote: From: Arslan Munir munir.ars...@yahoo.com Subject: [ns] Fw: transmission power change for one node only To: ns-users@ISI.EDU Date: Thursday, April 30, 2009, 8:41 PM Just forwarding it again as I was not sure whether sent or not as I am not getting the email that I send to ns-users. - Forwarded Message From: Arslan Munir munir.ars...@yahoo.com To: ns-users@ISI.EDU Sent: Wednesday, April 29, 2009 9:15:19 PM Subject: transmission power change for one node only Hi all, Does any body know how to change the transmission power Pt_ for only one node?

[ns] Changing transmission power too often
Well, I want to change my transmission power very constantly, but I am not managing to do so. Aparently, after some changes its value just stop being updated. Here is what I am doing to change it: In my tcl code: 61set phy_($i) [$node_($i) set netif_(0)] In my C++ code: 52 tcl.evalf($phy_(%d) set Pt_ %f,a_-myaddr,Pt_array[tt]); Some of the first changes do really occur, but from a point, the rest of them do not take effect at all, and I do not know how to manage to change it often. Anyone have a suggestion? Thanks, -- Fernando Henrique Gielow - UFPR - NR2 Computer Science graduation student.
[ns] Multiple transmission power settings
Dear ns-users, I have a simulation scenario setup with two wireless networks -- one network is running the DSR protocol and the other is running AODV in promiscuous mode. Is there a way to adjust the settings in ns2 so that the AODV nodes can transmit farther and faster than the DSR nodes? And which settings get adjusted? Essentially there will be two settings: one for DSR and one for AODV nodes. Thank you.
[ns] Packet Transmission Power control
Hi all, I am new to Ns-2. I am interested in implementing the simple power control scheme. i.e. RTS/CTS are transmitted at highest power and the Data/ Ack are transmitted at desired power calculated with the exchange of RTS/CTS. If so I have to change the C++ code for which I am not sure where and what changes to make? Any hints will be appreciated and if someone has done please guide me. And I have read the [ns] [PATCH] Per Packet Transmission Power this article And change the file the above mentioned, but I found that my receiver can't receive anything Did anyone use the same method above and can give me some hint. Best Regards, Jeff
[ns] Tuning transmission power
Hi all, I'm a (very)new user of ns2. I have to implement a mac protocol based on csma which is able to change the transmission power (and so the transmission range) dynamically. Can I do it by simply putting tcl commands such as the following one? $ns at 0.2 $node_(0) set TxPower_ 8.5872e-4 If not, I have to change the c++ code of ns2 in some way? I have read a lot of manuals and tutorials, but I didn't understand what I have to do.. Thank you in advance for the help francesca
